Hobby box opening - Soul of the Duelist - Yugioh

I do rarely buy old boxes with the intend to open them right away - this time i did! Soul of the Duelist was the first TCG set to introduce Ultimate Rares. The Armed Dragon line and the Horus, the Black Flame Dragon Line are great cards to pull and some goat format ultility cards like Master of Oz, Mystic Swordsman LV2, Mobius the Frost Monarch and Ninja Meastro Sasuke can be pulled, too, so what could possibly go wrong?
